3DS files are 3D models generated by the use of 3D design programs. There's nothing about them that's specific to Celestia. Well, is this the case or not? There still seems to be some confusion about this. If 3ds is a standard 3d format then it can be considered output from those other programs, an...

Sorry to have caused all this confusion, but I'm finally starting to understand this stuff now. The fact that 3ds files are basically 3d-graphics files and that images can be kept outside makes things much easier. So, for each script or 3d-graphics file that is read in by Celestia, the copyright bel...

Does this answer your question? Yes, thanks. Now I'm starting to get it. Sorry about all the fuss. :oops: So, are those the main kind of plug-ins? The script files and the 3ds files? Those sound ok. That just leaves the issue of the image copyrights; how does that work? Are you ok to include those ...

The 3ds files seem to be in a binary format, ie. not text. (binary does not have to be executeable). AFAICS the images are included in these files.

I trust you realize that if you insist on such an interpretation, many Addons (most of mine, for example) will have to be withdrawn from public availability. As I pointed out earlier, many are derivative works based on images which are not and cannot become GPL'd. Hmm. Yes, sounds like a problem. A...

Ok, so I just downloaded stardust.zip from Jack's site, containing an .xyz file and a xyz.ssc file, which both seem to be simply parameter files, so in such a case you are right. Are any of these plug-ins acctually compiled? (sorry, I'm new to this stuff {despite having a big mouth :oops: } ) I gues...

Is this really true? IANAL, but I would not consider an addon a "derivative work" of celestia, as it itself does not use or incorporate parts of celestia. It may be useless without celestia, but that's not the point ;) 1. Quote from the GPL: "If identifiable sections of that work are not derived fr...

Celestia is distributed under the GPL, and it is EXPLICITLY REQUIRED by the GPL that any 'derivative work' also be distributed under the GPL. ... ... If they did, Chris could sue them under intellectual property law. AFAIK, he's never limited what he considers to be a derivative work. Wow! I didn't...

Dear Celestia community, First, let me thank you for making such a great space simulator, and for making it available as open source. It has been included in both editions of our disc, TheOpenCD. People who get the disc always give good feedback on Celestia, and often mention it specifically. Also n...
